INVENTOR WITNESSES:

To all whom it may concern:

STATES MRTHELE GUGLIELMO on Be it known that I, MICHELE GUGLIELMO mi SIMONE, a subject of the King of Italy, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvemeats in Coffee-Making Machines, of which j of the roas the following is a specification.

This invention relates to coffee making machinery and has for its object ,to provide an apparatus which will receive ra-w cofi'ee berries and preferably deliver a deooction of coffee ready for drinking. Preferably the several operations of roasting, grinding, infiising, etc., are duly arranged in time according to the quantity and quality of the coffee to be treated.

The machine-provided by the invention in its preferred form comprises a roaster, a

istiller, a grinder, and an infusing device, which are adapted to roast the coffee, tocollect from the roasted coffee the vapors which are given off, to grind the roasted cofiee, and to prepare the coffee decoction ready for drinking. Preferably a boiler for water is provided and means for leading the boiling water to the ground coffee, and preferably also the products of the distiller are turned into the .decoction either directly or through the body of ground coffee being treated. Preferably also the above-named devices-are controlled successively and automatically in their several operations.

The accompanying drawings illustrate one cons 'ruction of apparatus made in accordance with this invention.

Figure 1 is a sectional elevation. Fig. 2 is a :part side view of Fig. 1, looking from the left. Fig. 3 is a horizontal section on the line 33 Fig. 1. Fig. 4 is a diagrammatic view showing the connection and operation of the controlling mechanism. Fig. 5 is a plan view of a detail of the timing mechanism. V a is a conical roasting chamber heated by a lamp 6. It is to be understood that any form of heating device may be employed according to the size of the apparatus. The

' roaster a is provided with a stationary agitator a and the roaster-is adapted to be rotatedbya shaft '0 operated by a handle, an

electric motor or-other means. The shaft 0.

isconnectedto the largerand innermost end ter which is closed by means of amour, 'or mew YORK, n. SCAVULLO, or new roan, N. Y.

a spring door d, the outer end of the roaster is provided with a curved hopper 6 with a covering cap e adapted to be tightly closed when the roaster has ries. The roaster is preferably proportioned to receive a definite quantity of berries whereby the amount to be dealt with in the apparatus is determined, it being only necessary to fill up the roaster. When the coffee is roasted itisdelivered through the door d to the distiller f where it rests upon flaps f disposed above the grinder It An agitator f is driven from the shaft 0' bevel wheels f. This agitator is adapted to stir up the roasted berries, the vapors from which pass upward into the condenser g by means of the bent tubes 9' which direct the vapors on to the top of the water disposed in the condenser whereby the said vapors will be condensed and combined with the water in the condenser.

After a certain period the flaps f are depressed to dotted position and the berries fall into the grinder h which is of any suit able kind and is driven by a shaft k which is a continuation of the agitator shaft.

is a boiler which surrounds the roaster above the lamp 6. The boiler is preferably closed by a safety val-veas at 70' adapted to keep the boiler at such a pressure that ;the water when used for making the coffee will exceed the ordinary temperature at which From the boiler the water is led through a controlling valve .m to a sprayer n disposed above the strainer i into which the ground coffee is delivered. trolled pipe 9 delivers the essence or liquor from the condenser 9 through another sprayer g g is a tap by which the coffee is drawn off into cups as required.

Referring now to the controllingme'chanism which is shown most clearly in Figs. 3, 4 and 5 of the apparatus, this mechanism may be disposed at the side or adjacent to A similar valve conthe central partition 00 of the apparatus.

The shaft 0 is connected through suitable gearing consisting of single toothed wheels 1' r and intermediate toothed wheels 7- r with a cam shaft 8 upon which are mounted lever 41 may control a valve 9 in the pipe 9 which permits liquor to flow from the condenser to the rose 9 which operates a spring pressed valve-m. I

A cam 8 operates a lever to which moves inwardly a spring-pressed valve m which allows water to'pass from the boiler to the spraying rose a.

In operation the lamp 1) being lighted the required quantity of coffee berries are placed in the roaster a through the hopper e which is then closed. The handle 0 is rotated which rotates the roaster a and also the shaft 0 of the timing mechanism. As

soon as the shaft 0 has been sufiiciently rotated the cam 8' operates the lever t and the door 03 opens by its spring and the roasted berries pass out on to the flaps f f. Here they rest and are stirred by the agitator f. This part of the apparatus constitutes the distiller and the vapors from the roasted berries rise and pass into the condenser 9 through the bent pipes y where the vapors are condensed and deposited in the water and form a liquor containing these essences of the berries which would otherwise be lost. The continued movement of the bandle brings the cams after the required period into such position that the lever 'v and pawls '0 release the ratchet 'v and the flaps f f drop by gravity or spring action and the cofieeberries fall into the grinder h where they are ground by the continued movement of the handle a. The ground coffee falling into the strainer '5 at or about the same time that the lever 11 releases the valve 9 and the liquor from the condenser is discharged into the ground colfee as it accumulates. At or about the time when this operationis complete the cam s operates the lever w and opens the boiler valve m'and the hot water from the boiler is discharged through the rose at on to the colfee in the strainer i and into the tank or receiver j by which operation the preparation of the coffee is complete and the same can be drawn oil by the tap 9 from the receiver 9' into cups or otherwise as required. As soon as the boiler is discharged another controlling device connected to the handle may release a gravity or spring actuated extinguisher which puts out the lamp. The flaps f fwill be restored toclosed position by the disk v and the door (1 closed when the apparatus'will be again ready for use. The timing of the apparatus may 'be regulated by adjusting thepqsition of the cm s, a suitable external indicator being provided showing the right position for a given quantity of coffee.

It is to be understood that otherequiva lent arrangements of controlling and timing mechanism may be substituted forthat described and shown, and also that an electric motor may be substituted for the handle and the apparatus will be otherwise modified in shape according to dimensions and the amount of coffee to be treated at one time. 1

While I have shown and described the preferred form'of apparatus, itwill be underst-ood that various parts thereof may be utilized without departing from the invention. 1
